Research On Chemical Industry Supply Chain Risk Management

Recently there are not a few accidents in chemical industry supply chain, such as releasing of chlorine, leaking of oil tanker, earthquake, terrorism, warfare, mouth-foot disease, SARS and tsunami etc. Chemical industry supply chain is tremendously affected by these risks, moreover many companies are broken down for the collapse of supply chain. Such accidents bring uncountable loss not only to the upstream and downstream of supply chain but also to environment and safety of lives. Thus researching on chemical industry supply chain risk management has very important practical significance for strengthening the operational security of chemical industry supply chain, prompting the sustaining development of chemical industry supply chain, enhancing the competence of chemical industry, reducing the exhaust of global energy sources and resources, and protecting environment. It also has very important academic significance to present guidance and support on theory and technology for the supply chain risk management practice of chemical industry companies, and to help to the theory development of supply chain risk management.This dissertation mainly includes seven chapters, which are stated in detail as following.Chapter one is introduction. This chapter introduces the research background and gives literature review, then states the research significance, finally presents the technology routine and content arrangement of the dissertation.Chapter two is basic risk analysis of chemical industry supply chain. This chapter gives the definition and classification of supply chain risk, concludes the features of chemical industry supply chain by analyzing the actuality of chemical industry, and analyzes the basic characteristic of chemical industry supply chain risk further. Finally the theoretic structure of chemical industry supply chain risk management is presented.Chapter three is risk identification of chemical industry supply chain. After researching the features of chemical industry supply chain and refining the sources of chemical industry supply chain risk, this chapter classifies chemical industry supply chain risk through positive analysis. Then two representative individual risks are identified further more. The sources of transportation risk are induced through transportation process analysis, and the sources of green risk are concluded by fault-tree analysis.Chapter four is risk assessment of chemical industry supply chain base on risk classification. Firstly this chapter presents risk assessment structure of chemical industry supply chain according to risk classification. Secondly collective risk of chemical industry supply chain is assessed by rough sets theory to distinguish the significance of individual risks, which is helpful for individual risks control. Thirdly after modifying traditional transportation risk assessment model according to the features of chemical industry supply chain, a dual model is developed for transportation risk assessment of chemical industry supply chain, then risk assessment process and numerical example are presented. Finally the green risk assessment index system of chemical industry supply chain is designed on the basis of green risk identification, and fuzzy comprehensive evaluation model of green risk is developed, then assess process and numerical example are presented.Chapter five is risk control of chemical industry supply chain based on risk ranking. Firstly this chapter gives the risk control structure of chemical industry supply chain according to risk ranking, and presents qualitative risk control measures; secondly chance constraint model of collective important risk control is developed by analyzing the trade-off between risk control cost and risk control benefit, then numerical example is presented; thirdly the goal programming model of transportation disruption risk control is developed to reduce the loss of internal and external of supply chain as possible, then numerical example is presented; finally the fuzzy programming model of green important risk control problem is developed and numerical example is presented to analyze further.Chapter six is an implementation of chemical industry supply chain risk management base on 3S. This chapter presents integrated framework of 3S and chemical industry supply chain risk management, gives implementation steps, and presents main implementation plans, such as drawing out of risk map for risk assessment, transportation routine optimization for risk control, assistant disposition of risk accident, evaluation and recover of risk accident.Chapter seven is conclusion and future work. This chapter draws the conclusion of this dissertation, moreover presents the research innovation and future work.The innovation of this dissertation mainly contains four aspects as following:(1) After studying on the features of chemical industry supply chain and the basic characteristic of chemical industry supply chain risk, the theoretic structure of chemical industry supply chain risk management is presented by adopting and partly modifying various theory and technology of risk identification, risk assessment and risk control, which enriches the theory of risk management. On the basis of literature analysis and positive research on chemical industry supply chain risk, the dominating risk resources of chemical industry supply chain is identified, which can be classified as collective risk and individual risk. Individual risk can be classified as transportation risk, green risk, production capacity risk, partnership risk and information risk, which is helpful for risk classification.(2) This dissertation gives the risk assessment structure of chemical industry supply chain, which mainly assesses collective risk and representative individual risk (transportation risk and green risk) and ranks the risks according to the results of risk assessment. In the view of assessing the risk aftereffect on the internal and external of chemical industry supply chain, a dual model for transportation risk assessment is developed innovatively after modification of tradition transportation risk assessment model, then transportation risk can be ranked as daily risk, generic risk and disruption risk according to the comparison between the result of risk assessment and risk parameter. The green risk assessment index system of chemical industry supply chain is designed, and fuzzy comprehensive evaluation model of green risk is developed, then green risk can be ranked as daily risk, generic risk and important risk according to the result of risk assessment.(3) This dissertation presents the risk control structure of chemical industry supply chain based on risk ranking, which is to ignore the daily risk, give qualitative risk control measures for generic risk and build quantitative model for disruption risk or importation risk control. Chance constraint model of collective important risk control is developed by analyzing the trade-off between risk control cost and risk control benefit, thus it can improve risk control effect through optimizing risk control measures under restricted devotion. This dissertation considers the impossible loss of disruption risk as social cost, and the goal programming model of transportation disruption control is developed to reduce the loss of internal and external of supply chain in the view of comprehensive optimizing individual transportation cost, custom dissatisfied cost and social cost, then presents disruption risk control measures through analysis of numerical example. The fuzzy programming model of green important risk control problem is developed to optimize the production planning, while regarding three important risk sources of green (i.e. resource, energy and environment) as constraints of the model.(4) 3S (GIS, GPS, RS), the intercross subject theory and technology is utilized for implementation of chemical industry supply chain risk management. The integrated framework of chemical industry supply chain risk management based on 3S is presented, then the implementation steps and principal implementing scheme is given. Chemical industry supply chain risk management based on 3S can do spatial information visualization and analysis, which can be helpful for the academic development of traditional supply chain risk management.
